Denis covered this in depth
, but I thought I'd mention the Toronto Screenwriting Conference
happening this weekend. They've got some pretty exciting speakers, like an Exec Producer of THE SIMPSONS, and the writer of ZOMBIELAND and a Co-Exec Producer on HOW I MET YOUR MOTHER and the showrunner of STARGATE. And they've all promised to talk in depth about craft, and not just tell war stories. It sounds like the sort of thing that you could come away with some real nuggets of craft. And, you'll meet lots of fellow screenwriters and maybe some producers and even execs. If you're within striking distance of Toronto, definitely check it out.
